Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B
The AirTAC ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B is a genuine double acting, double rod, adjustable stroke ISO 21287 compact air cylinder with a Ø100mm bore and 300mm stroke, 1/8" air ports and a hard-anodized aluminium body. Its short compact envelope saves about 50% of the mounting length of an ISO 15552 profile cylinder.

About the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B
A double acting ISO 21287 compact cylinder with an adjustable extend stroke, the ACEJ100X300-20B pairs a 100 mm bore with a 300 mm stroke and a male (B) rod thread. At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push rises to 5497.8 N, with a theoretical 800.9 kgf at 1.0 MPa. The external stop screw trims the extend stroke anywhere in the ordered 20 mm window, so the working range is 280-300 mm without changing the cylinder.
The short ISO 21287 body saves about 50% of the mounting length of an ISO 15552 profile cylinder, which matters on long-stroke presses and gantries where envelope is tight. Hard-anodized aluminium body, S45C hard-chrome rod and a fixed TPU bumper at each end handle daily cycling at 30-500 mm/s.

Specifications follow the official AirTAC ACE-series (ISO 21287) datasheet. Body: hard-anodized aluminium alloy; piston rod: S45C carbon steel with hard-chrome plating. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G. A built-in magnet is OPTIONAL — add the -S code to fit CMSE / DMSE position sensors.
Theoretical Output Force (Ø100mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 3770 N |
| 0.7 MPa | 5278 N |
| Max (@1.0 MPa) | 769 kgf |
ACEJ is double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B Is Used
Gantry clamp on a machining cell
The short ISO 21287 body fits under low gantry beams where a full-length profile cylinder would not, clamping castings during CNC second operations.
Is the Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B the Right Cylinder?
The -20 stop screw only shortens the extend stroke within 20 mm - it is a mechanical end stop, not a mid-stroke lock, so the rod still drifts if air is lost. Mount on the ISO 21287 face with FA flange or LB foot plus I/Y rod knuckles. This unit has no magnet; order the -S code if CMSE / DMSE switch positions are needed.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Short stroke fits the compact body
- ✓ Port/thread type (PT / G)
- ✓ Add -S if you need the magnet for sensors
- ✓ Rod type (female / male B) & mount (FA/LB/CA)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Compact body: keep the stroke short and avoid side load on the rod.
- check Do not dismantle the threaded front/back covers.
- check Keep speed within the rated range; the TPU bumper absorbs stroke-end energy.
- check Installation by qualified personnel per AirTAC docs.
Airtac ACEJ80~100 Adjustable Compact Cylinder ACEJ100X300-20B FAQ
At 0.5 MPa it pushes 3927 N and pulls 3769.9 N; at 0.7 MPa push is 5497.8 N and pull 5277.9 N, with a theoretical maximum of 800.9 kgf at 1.0 MPa. The -20 code gives a 20 mm adjustment window: an external stop screw shortens the 300 mm extend stroke to any setting between 280 and 300 mm. It is a mechanical end stop only - on air loss the piston drifts, so it does not hold a load. Operating range is 0.15-1.0 MPa (22-145 psi), speed 30-500 mm/s, air filtered to 40 um.
It is an ISO 21287 compact cylinder whose short body saves about 50% of the mounting length of an ISO 15552 profile cylinder, with a hard-anodized aluminium body, S45C hard-chrome 20 mm rod, 1/8" PT ports and a fixed TPU bumper at both ends. FA flange, LB foot and I/Y knuckles bolt to the standard face. Position sensing requires the optional -S magnet, ordered as a separate code; this model has no magnet fitted, so CMSE / DMSE switches cannot be mounted unless you specify -S.
